BTW, The title of this topic has become a wee bit of an understatement.

I can rename it, if you would like a more appropriate title for what it's evolved into.

Thank! A new title is a good idea.

It's your topic, so let me know what you come up with. Or we could just add, "and then some..."

Wow! Nice looking project you have going on there, you should have some nice low end grunt on tap. 1 ton up front should be about unbreakable. Are you going with a locker also?

We are test fitting the exhaust now that we have the alt and ac compressor installed

Machined the crank sensor pulse pattern into the 4bt cummins harmonic balancer so the stock jeep tj tach will work

Turbo clearance has been an issue but might have found a solution by turning the charger 90 degrees

Test fit looks decent so far

Got to spend a few minutes working on the next piece of the exhaust

There isn’t much room for anything but engine under that hood.

I have been dragging my feet on this project but have made some good progress lately

Looks nice and clean!

Not sure if it's still a mock-up but I'd be a little concerned about the oil feed hose routing to the turbo in the picture..

Seems it's now running between the manifold and the downpipe. Could get awfully hot there even though it's a diesel and the peak exhaust temps are way lower than a gas one. PTFE (lined) hose can run up to 400F or so, but it will start degrading from that point onward. Also seems a little un-supported which could cause issues with the vibrations and weight of the hose cracking the fitting/connection to the turbo in the long run. (what? a big diesel having vibrations? nooooo.. of course not! )

Spraying hot oil over a turbo or manifold usually in the 'uh oh.. I think this is not so good' category

Could you perhaps run the oil hose from the block under and away from the manifold, towards the firewall and then up the firewall to get to the turbo from the other side? Just so it's far away from any 'hot pipes' as possible and with as little strain/stress on the hose and fittings?

Bye, Arno.

That little 4bt should be a beast in that TJ, interested in seeing what your fuel mileage improvement will be?
